To update your package list:

apt-get update

To install any newer packages that may have been added to the repository:

apt-get upgrade

apt-get upgrade will automatically list all of the new packages and then ask you if it is ok to start upgrading them.  If some of the packages require additional packages, it will hold off on upgrading those and their dependencies until you manually update them.

Apt package access is controlled via the /etc/apt/sources.list file:

For example (Debian Lenny):

deb http://mirror.csclub.uwaterloo.ca/debian/ lenny main contrib non-freedeb-src http://mirror.csclub.uwaterloo.ca/debian/ lenny main contrib non-freedeb http://security.debian.org/ lenny/updates main contrib non-freedeb-src http://security.debian.org/ lenny/updates main contrib non-freedeb http://volatile.debian.org/debian-volatile lenny/volatile maindeb-src http://volatile.debian.org/debian-volatile lenny/volatile main

Your system will probably be set to obtain updates from a different repository address and may not be set to access the contrib and non-free repositories.  If you comment out everything except the lines referencing security.debian.org, run apt-get update, then apt-get upgrade. The packages listed then would just be security updates.

you might want to add contrib and non-free to your security update lines too.
